yinnninenioUNTronrnows'ann oriinfieafmnsh To a'ZZ 'ze/wm #may concern: i v IBe i knownthat I, ELoN DUNLAP, a citizen of the United States, and a resident of Diamond Spring, in the county of` Eldorado Aand State of California, have invented a new and Improved Yielding lMount for Flows and other Tools, of which thefollowing is aifull, clear, andexact description.

My invention has for its object to provide a mount `for plows` and other tools, which will permit the vplow or other tool to 'pass over l'an' obstruction, such as a stump orr roclc, and still make vit impossible for the plow 'pr'otherhtool to be drawn out ofline when' passing` through an obstruction' of less resistance, such as a hard spot in the soil. The plow or other'tool is held in normal position by'resilient means, the tension V of which increases with the pull up to apre-` determined point, when the further move-` ment ofthe plow or other tooll may take place more readily. This resilient ymeans may-be so adjusted that the point where thel resistance of the plow or other, tool becomes less, may be set yat. a predetermined number of pounds `draft orchanged as' desired.

Anotlierobject rof the invention is to provide a spring for holding the plow or other V tool in fnormalposition, 4which permits the 30 movement of the.v plow out of normal position when, the strain becomes excessive. In addition to the spring, pawls are provided for holding the plow or other tool rigid in .normal position and also for holdingl the plow or other tool out of vnormal position untilv ant/obstruction 4has been. passed. The plow or other tool will .return immediatelyy toy normal position `and in alinement after the passing of the obstruction.

Additional ob ectscl of the invention Awill .appear'in the following specification, in

' which the preferred form of my invention is disclosed.'

. In the.: drawings similar reference characters, refer to simllar parts 1n all the vlews,

in Which my invention is illustrated asap-.- pliedto a plow,` Y 'l i Figure 1 1s a side elevation of a plow.,

side elevation in section, similar to that [Patented Mar.

shown in Fig. 1, but with the plow rotated 1 u lalso beunderstood that a plurality of mount- 1 ings may be supported by 'a .single frame,

so that a gang of plowsfm'aybe operatedgby the same power, the drawings mereiy show my invention as applied to a single-plow.

However, itV will. be understood that fthe principle is the same`whether one or more plows are\mounted on the frame, orwhether other tools are: substituted for the plows, one of which is shown in the drawings.-

it will be seen by referring to the drawings, that a beam 10 is provided, having por.

tions 11 and 12, which are disposed substantlally parallel with each' other, the portion 11 above the portion 12,-these portions being.

connected bya curved portion 13, the center line l.of which is disposed at acute anglesV ,relatively to the portions 11 vand 12 of the beam 10. .Mounted for traveling longitudinally on the portion 12 of the beam 10, there isa 4carriage 14, which serves as a tool car'- rier, ahead 15011 a plow 16 being secured to this carriage 14 as indicated in the drawings.

The carriage 14 may 'have' severalv rollers `for` ear .24 on the beam 10. It will be seen that by turning the screw 2 2, the tension of the spring 19 maybe .adjustedand thatwhen adjusted, thescrew 22`may be held 1n its position by the lool; nut 25, whichl meshes with the thread on the screw 22.

It will be seen that the vplow with its thplow l16 strike a stump 27 or other unward movement of thev plow 16 with itsl usual obstruction, i it will be moved rearder the influence of the stump or other obi. struction 27, the plow 16 will be rotated to the rear of the portion 13 n of the beam 10, illustrated in, F ig. 6 of the drawings. Fig. 4 of'the drawings,'llustrates the rear I head 15 andthe carriage .14'. under normal conditions, and as stated, Fig. 6 illustrates the rotary movement of the carriage 14 and the'plow 16 when the4 plow. strikes an unusual obstruction. The axis'ofvrotation of the carriage 14 and the plow 16 when thel plow moves rearwardly of the portion 12 of the beamlO, is the step 29 and the rollers 18 on the carriage'14. The' beam10 is piv- .'oted at its forward endto. a transverse stud l 30 secured to .members'of the frame 26,'the

' portion 12 ofl the 'beam 10 being disposed in a guideway 31,v formed 'bythe rectangular members 32,-which are secured to the under- -side of thel frame 26. It will therefore be seen that any lateral movement of the beam v,10 relatively"to-the1framei26 will be prevented. The portion\ 12 of the beam 10 is normally heldrigid relatively to the frame 26, in the position indicated in Fig. 1 of the drawings, by pawls 33 and 34, the pawls 33 engaging. the upper side of the portion 12 of .the beam and the pawls 34 engaging the bottomi of the .said portion 12 of the beam. )These pawls-33 and 34- are held yieldinglyv iii this position-by the springs 35. Secured frsli'ding on the portion 12 of the beam 10,K there is a sleeve 36, which is connected by; links 37 with the carriage 14, so `that it l 'f willlgglbe `moved therewith. This sleeve 36 `lca'ri-"l"e"s two upper and twolower wedges 38,

" which are disposed in front of the pawls l33 and 34 `and which engage the pawls33 Aand 34 topush them away from each other when the. 'sleeve 36 is moved rearwardly with the rearward movement of the carriage 14.. This bein@ so,-when the carriage 14 moves rearwardly from' normal position and when the rollers 18' on the carriage engage the' stop 29, the wedges 3S on the sleeve 36, free the pawls 33 and 34 from the portion 551 iframe 26, this freedom of movement being important in order'that the plow 16 may .the plow 16 become disengaged from the stump 'oi-A A12 f the beam 10, so that the beam 10 is free to be moved vertically relatively to the disengage itself from the stump or other obstructionl 27. However, as it is important thatthe beam 10 be moved upwardly with 16, to make certain that the plow other obstruction 27, I provide one or more leafs'prings 39 which are mounted on the transverse stud 30 and which are disposed- 'on the side members 32 -when -the beam when the-carriage 14 moves rearwardly out -of normal position and is rotated as indi- .eated in Fig-6 of the drawings, it pulls the link 44 rearwardly thereby bringing the roller 45 on the arm 41 into engagement with tlieunderside ofthe spring 39 to press thespring 39 upwardly, thereby serving to raise the beam 10 to a position where it will be disposed above the pawls 46 to be supported thereby, these pawls being mounted of the guideway 31 and being held yieldingly 4in position by the spring 47. In this position the plow 16 will be supported until the obstruct-ion has been passed, when the spring 19 will pull forwardly the carriage 14 and with it, the

plow 16, the wedges 4 8 on the carriage 14 engaging the pawls 46 to push the said pawls 46 out of rcontact with the beam 10,

Y10 will be -pushed downwardly not only by gravity, but by the spring 39 under the influence of the roller 49 mounted on the arm 50,. which is pivoted to a member 51 of the fra eat 52, this arm 50 being-moved forwardly by the link 53 which connects the carriage 14 with Athe said arm 50. At the saine time, the arm 41 is moved forwardly as indicated in Fig. 1 of the drawings, with its roller 45 out of contact with the spring 39. the beam 10`and the carriage 14 with the plow or other tool 16 is brought back to normal position, a buffer spring 54 being mounted below the portion 12 of the beam 10 for engagement by the head 15 of the plow 16, to lessen the shock.

It will of course be understood that when the arm 41 is moved rearwardly, so that its roller 45 w-illu engage the spring 39 to raise the beam 10, that the arm 50 will be moved rearwardly byits link 53, so that its roller '.will be out of engagement with the spring 39. In the drawings, I show two springs 39, one disposed at each side of 10 and a pair of arms 50 disposed above the springs 39 and a pair of arms 41 disposed below the said springs. The portion 11- of the beam 10 is disposed in a vertical guideway 55. The frame 26 is mounted on wheels 56,v so that it may be readily drawn by draft In this manner the beam `cally raising the' beam on the movement of y f the tool-carrying' means` thereon.
